Mental issue of wife - but she is not giving divorce

After my marriage I found my wife is not normal like other girls.. She doesnt use to talk much neither she has friends nor she goes outside. Even she doesnt used to talk with me also. Then we found after 5 months of marriage that she has depression.. She had depression attack she doesnt used to talk or eat just she used to sit and cry only.. We had her treatment. Her family denied for any medical history..she used to talk mad things and gave us suicide threats But gradually when she was ok than she confessed that she has taken treatment twice for depression.. She went back to her home.. Than she recovered.. We forget everything took her back to our house.. She was normal doing everything fine again after 2 days she got depression attack we changed doctor also.She was not ready to live with me.She was trying to jump from terrace, we saved her. And then she asked to go back to her home. We send her.Than after going there after some day she is now normal so they are blaming my family.
